Abstract

The invention relates to a nanostructure for selective infrared stealth with different polarization states, comprising a micro-channel heat dissipation layer with a thermoelectric conversion layer arranged above the micro-channel heat dissipation layer, and an ultra-black material absorption layer disposed above the thermoelectric conversion layer layer, the ultra-black material absorption layer is composed of a plurality of periodically arranged Swastika-shaped structures; the nanostructures of selective infrared stealth with different polarization states can not only convert light into heat energy, and then convert heat energy into electrical energy, through light ‑thermal and thermal‑electric conversion convert the energy absorbed by infrared into electrical energy that can be collected, and the electrical energy can be used directly, which not only improves the stealth effect and lifespan of infrared stealth materials, but also selectively absorbs incidents of different polarization states to achieve The effect of stealth can also be used as a detection analyzer to identify different polarized light.

Description

technical field

[0001] The invention belongs to the technical field of infrared detection, and in particular relates to a nanostructure with selective infrared stealth in different polarization states. Background technique

[0002] With the rapid development of electronic information technology and its wide application in the military field, the means of military reconnaissance have achieved high-tech. In the situation where battlefield targets are "hit when found", the advent of infrared imagers has made the once effective visible light and radar stealth technologies face the threat of being cracked. When the atmospheric conditions are good, the airborne infrared search and track system can detect the target at a distance of more than 80km. Therefore, on the basis of visible light and radar band stealth, taking into account infrared is an inevitable trend in the development of full-band stealth technology in the future.

[0003] In recent years, the high-precision, intell...
